# Missing Data

This folder includes code used for the estimates in the "Missing Data" section of the "Missing Data, Speculative Reading" article.

*NOTE: most of the Jupyter notebook files were originally created and run on Google Colab. Several of these notebooks are too large for GitHub's preview; it may render output blocks as empty when they are not.*
